BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a backpack, and more particularly to a backpack with supporting structure.

2. Description of the Prior Arts

As a tool for carrying objects, bags vary from the early handmade basket and the handbag to the current plastic, Synthetic Leather or other material made bags, including suitcase, wallet, lady handbag, school bag, backpack and the like.

Different bags have different specialties, for example, the shopping bag maybe not beauty in appearance but should be foldable for easy storage, and the lady handbag is normally provided with a support structure for protecting the objects received therein. And most of the backpacks available on the market are soft in structure and unable to well protect and effectively tidy up the objects received in the bag, so that the objects are always in a mess. As shown in FIG. 1, a conventional backpack is usually made of flexible non-woven material and generally comprises a front part 31, a rear part 32, a bottom 33, a first side 34, a second side 35 and zips 36, 37 on the first and second sides, the first and second sides 34 and 35 define two receiving spaces. Since it is made of flexible material through sewing process, the backpack is not only high in production cost, but also too soft in structure, failing to provide strong support to the objects to be received in the bag, so that the objects will always be in a mess.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a backpack with supporting structure capable of providing strong support for the objects received therein.

A backpack with supporting structure in accordance with the present invention comprises a front part, a rear part, two opposite sides and a plurality of partitions, wherein the two opposite sides are connected to the front and rear parts by hot melting, each of the two opposite sides comprises at least two a first and a second sheet members, the partitions are disposed between the front and rear parts to form a plurality of receiving spaces, on the two opposite sides are arranged zips, an end of the first sheet member is connected to a lower end of the second sheet member by hot melting, so as to form a foldable portion that is connected to the partitions by hot melting.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2 and 3, a backpack with supporting structure in accordance with the present invention is shown and comprises a front part 11, two opposite sides 20 and a rear part 13. The front part 11 can be provided with different pockets according to needs, and the rear part 13 also can be provided with belts, pockets or the like according to needs. On the two opposite sides 20 are arranged two zips 14 and a hard plastic made partition 15 is disposed between the zips 14, defining two receiving spaces therebetween. The two opposite sides 20, the front and rear parts 11, 13 are integrally connected to one another by hot melting, so the assembly of the this backpack will be more time-saving than the conventional one. The two sides 20 are made of flexible plastic in form of a circular framework, so as to form a strong structure of the backpack by cooperating with the hard partition 15.

The partition 15 is also integrally formed with the two sides 20 by hot melting, each of the two sides 20 comprises two a first and a second members 21, 22, as shown in FIG. 4, at the connection between the first and second sheet members 21, 22 and the zips 14 is formed an opening 27, so that the zips 14 can protrude out of the opening 27 for easy use. An end of the first sheet member 21 is connected to the front part 11 by hot melting, and another end of the first sheet member 21 is located beneath the second sheet member 22 and have a melting portion as indicated by 25 connected to the second sheet member 22 by hot melting, so as to form a foldable portion 26 that is folded down to be melted with the partition 15 by hot melting. And the partition 15 can be melted at the left or right sides of the foldable portion 26.

The number of sheet members and the receiving spaces can be varied according to needs.

While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention. 

1. A backpack with supporting structure comprising a front part, a rear part, two opposite sides and a plurality of partitions, wherein the two opposite sides are connected to the front and rear parts by hot melting, each of the two opposite sides comprises at least two a first and a second sheet members, the partitions are disposed between the front and rear parts to form a plurality of receiving spaces, on the two opposite sides are arranged zips, an end of the first sheet member is connected to a lower end of the second sheet member by hot melting, so as to form a foldable portion that is connected to the partitions by hot melting.
 2. The backpack with supporting structure as claimed in claim 1, wherein the two opposite sides are in the form of a circular frame made of flexible plastic.
